Page 5: Operation
Between the light-entering prism (1) and the refracting prism (2) there is a small gap, in which the liquid to be measured is placed. When a light beam (natural light or incandescent light) enters the light-entering prism (1), a diffuse reflection will be caused on its frosted surface; therefore, incident rays with various angles in the liquid to be measured will, via the reflecting prism (2), form a light beam with reflection angles larger than the angle of emergency. - Page 6 5.1.2 before performing the measurement and making the calibration of the indication each time, the dull surface, the polished surfaces of the reflecting prism and standard sample should be cleaned with absorbent cotton soaked in a mixed solution of absolute alcohol and diethy1 ether (1:1), so as to remove other foreign substance which will affect the sharpness of image and the accuracy of measurement.
